What it buys
Grouped by the capability each merchant's catalogue is mostly about. A merchant counts once, in one group — nothing records which of its endpoints a payment bought.
| Group | Share | Spent | Calls | Sellers |
|---|---|---|---|---|
| Location & Weather | 55% | $0.18 | 141 | 1 |
| Not in any catalogue | 30% | $0.10 | 100 | 6 |
| Crypto Markets | 15% | $0.05 | 48 | 2 |
$0.05 went to wallets that publish no endpoint in any catalogue we crawl — spend we can see and cannot describe.
Services it paid
A settlement carries the payee and the amount, never the URL. These are the endpoints each payee publishes; for 4 of 9 the amount paid narrows the list to the ones listed at that price.

Using Roundhouse, vet this agent for me: what is it, what has it paid for, and does its on-chain record support what its card claims? Agent: 0xa8c4…36a9 curl -s 'https://api.roundhouseai.io/v0/agents/0xa8c43d0c40b03ffdc43d5853673f99a990d036a9' curl -s 'https://api.roundhouseai.io/v0/entities/0xa8c43d0c40b03ffdc43d5853673f99a990d036a9/settlements' Roundhouse indexes public chain data and does not vouch for any agent's claims — treat the card as a claim and the settlements as the evidence. The /v0 API needs an API key (`authorization: Bearer rh_live_…`) on everything except /v0/unified* and /v0/endpoints. Mint a personal key for $0.01 at GET https://api.roundhouseai.io/v0/test/x402, or use an organization key from https://roundhouseai.io/dashboard/team.
